Corruption is a common Peerless Reagent that is used in the creation of certain Craftable Artifacts and Magical Craftables. It spawns on the corpses of Peerless monsters. There are two subtypes: reagents that only spawn on a specific peerless boss, and ones that can spawn on every peerless boss. Corruption is of the latter type.
Corruption is used along with other ingredients to create the following items:
| Blight Gripped Longbow|
Corrupted Rune Blade
| Luminous Rune Blade|
| Quiver of Lightning|
